A ball is thrown from a height of 40 meters with an initial downward velocity of 5 m/s. The ball's height h (in meters) after t seconds is given by the following. h=40-5t-5t^2
How long after the ball is thrown does it hit the ground?

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.

step-by-step explanation:

divide 13.5 by 9 to get the scale factor. it equals 1.5

2 * 1.5 = 3
